Arles to Appenzell: A Journey Through Provence and the Alps

Jutting from the Roman arena of Arles at 43.6766° N, 4.6276° E, your odometer starts at 0 km on the D570N, a road that shadows the Grand Rhône for the first 30 km. This route, spanning roughly 800 km to Appenzell at 47.3332° N, 9.4104° E, crosses three countries and four distinct climatic zones. The drive typically takes 8–9 hours of pure driving time, but few complete it without at least one overnight stop.

• Key highways: A9 (France), A1 (Switzerland), E25/E35 portions.
• Milestone: The 45.8° N parallel near Valence marks the transition from Mediterranean to continental climate.

French A9 autoroutes are well-maintained with rest areas every 20 km. The Swiss A1 is equally good, but once you exit onto cantonal roads toward Appenzell, expect narrow two-lane roads with sharp curves. Speed cameras are common in both countries; radar detectors are illegal in Switzerland.

• Rest zones ideal for families: Aire de la Palud (A9 near Valence) with a playground; Raststätte Würenlos (A1 near Baden) with indoor play area; Raststätte Knonau (A1) with pet exercise area.
• Pet-friendly framework: Most French rest stops allow dogs on leash; Swiss rest areas require dogs to be muzzled. The Appenzell region has many dog-friendly hiking trails.

Fatigue management is crucial: the most monotonous stretch is the A9 between Montélimar and Valence (110 km of straight road). Schedule a break at the Aire de la Coucourde (km 150) which has a coffee shop and panoramic view. In Switzerland, the A1 between Bern and Zurich can be dense; stop at Raststätte Gütsch near Lucerne for a short walk by the lake.

• Hidden off-route spots: The secret waterfall of Creux de l'Enfer in the Thiézac valley (1-hr detour from A9, exit 24); the covered bridge of St. Martin in the Goms valley (off the A9 at Brig).
• Climatic conditions: Arles averages 28°C in July, while Appenzell is 10°C cooler. In winter, the A9 near Lyon can have snow, but the Swiss passes require winter tires from November to March.

Tolls apply on the A9 from Arles to Lyon (approx. €15) and on the A1 in Switzerland (via vignette, CHF 40). Fuel costs average €1.80/L in France and CHF 1.80/L in Switzerland. Electric vehicle charging stations are plentiful along the A9 and A1, with fast chargers every 30–40 km.

• Best fuel stops: TotalEnergies at Orange (A9 exit 21) for competitive prices; Agrola near Bern for Swiss efficiency.
• Driving tip: The section between Sion and Brig in Switzerland often has reduced speed limits due to Alpine winds.

For an optimal experience, consider using how to find the best stops and hidden gems between cities to plan your breaks.

From the lavender fields of Valensole (detour via D8 at Manosque) to the limestone gorges of the Ardèche (a 20 km detour at Bollène), the first half of the route is a feast of Provencal textures. Entering Switzerland, the landscape shifts to the Vaud vineyards (Lavaux UNESCO site) and then to the Bernese Oberland peaks.

• Must-stop viewpoints: Belvédère du Pas de la Coche (Ardèche), Chexbres vineyard terrace (Lavaux), and the Säntis summit near Appenzell.
• Local commerce: Farmers' markets at Nyons (olives) every Thursday; Gruyères cheese dairy (detour 10 km); Appenzeller cheese cellar at Stein.

UNESCO World Heritage sites along the route include the Roman Theatre of Orange (A9 exit 22), the Historic Center of Avignon (short detour west), and the Lavaux Vineyard Terraces (A9 exit 15). The route also passes near the Rhône Valley's paleontological sites, such as the dinosaur eggs of La Bégude-de-Mazenc.
